Initial public release of the BiSpectral EEG Component Analysis (BiSCA) framework.

Paper: Wang et al. (2025) "The influence of nonlinear resonance on human cortical oscillations" — bioRxiv

Included

  • BiSCA model — joint spectral + bispectral fitting (package/HoXiAlpha/@BiXiAlpha/)
  • Bootstrap testing — Gaussianity and linearity statistical tests (@BiXiAlphaBootstrap/)
  • Higher-order spectra — bispectrum and bicoherence computation (@HOS/)
  • Figure scripts — reproduce all main paper figures (Fig. 1–4) from example/BiSCA/
  • NAR-LPR — nonlinear autoregressive local polynomial regression (utility/nar_lpr.m)
  • Demodemo_BiSCA.m walks through a single-channel BiSCA analysis
